or 27% more than the net present value of the estimated purchase price/relocation and occupancy costs, as well as the financion costs over a 30-year period that. would be an estimated $18.1 million. so our our conclusion because it includes new costs for the pucks, as compared to continuing to lease at the existing locations, therefore, we say it's a policy matter, even though we acknowledge that if the supervisors agree with the department to centralize in one location, it appears that the city would be getting a good deal. >> thank you, mr. rose. sean? >> mr. rose, and maybe this is puc too, and maybe you might not know harvey, the current lease analysis that you did, if we kept it for 30 years, what are the current terms of lease?
